I have 2 100 watt panels in parallel going into the 12 volts MPP Solar All In One box then into a 100ah LiFePO4 Battery. I live in Southern California. At the beach, on a clear bright, and sunny day, the box says those panels at 1:00 pm are producing 17v, 5a, and 89w. It is charging the battery but do these numbers sound right? Should they be more? Also at night without any load or anything plugged into the AC, the battery goes from 13.3 volts to 10.9 volts in a matter of a few hours. Any idea what is draining the battery? Thank you for your help, John Lyman
